Worth 1000

Worth 1000 (from the phrase "A picture is worth 1000 words") is one of the coolest websites I have ever found. I will warn you right now that if you do not have a lot of time to spare, you shouldn't look at it.
According to the website, Worth 1000 is two things: "a daily image manipulation contest site [and now also writing illustration and photography] and it’s also a gallery of all the entries ever produced for these contests." While this is a pretty good overview, I would add to it that it is also a great place for Photoshop Tutorials. I have found some of the coolest tutorials on this site, and they are pretty easy to follow and explain how to do some really cool stuff.
The other thing about Worth 1000 is the images that are stored there. As mentioned in the overview, it is a database of all of the entries from these contests, and some of the them are absolutely amazing! Here are some interesting ones: turtle sandwich, angry scarf, stepping through the door, and mechanical frog.
I haven't so far, but at some point, I am hoping to enter some of these contests just for the sake of doing so.

Vixy.net

Vixy.net is a cool website that lets you convert FLV (flash) videos (for example, YouTube videos), to AVI, MOV, MP4, or 3GP formats, and then download the converted movie. This is very useful for getting videos in a format that can be easily played on your computer (ie. MOV files can be played by Quicktime) or for getting a video in an acceptable format for upload by video upload sites.
I recently used Vixy.net to convert a YouTube video that I had uploaded to MOV format so that I could upload it to another website to enter a contest to win free Oakley products. It worked quite well, and I highly recommend it.
Here's how to use Vixy.net:
1. Enter the URL of the video you wish to convert
2. Choose the output format of the video
3. Click "Start"
4. When Vixy.net has finished converting your video, it should automatically ask you what you if you want to open the file, or save it. If it doesn't ask you, click on the "download video" link
5. Click "save" and choose where to save it

Twitter

Recently, during my computer wanderings, I came across a site that I had never heard of: twitter.com. Here is its basic premise: You create a membership, get a URL, and update your status. People who are interested in knowing your status can subscribe to your twitter and will be updated through e-mail, text message, or online whenever your status changes. It is an interesting idea, so I promptly joined (see twitter.com/uncoiled), but have realized since that I am not online enough to really learn anything interesting from following anyone's status. Also, I do not think that anyone I know is a twitterer, and there is really no reason for me to stay up-to-date on the status of people I do not know. I do understand how twitter would be useful though if your group of friends all used it and if you had unlimited texting capabilities on your phone (which I do not) because it is quick and easy to update your twitter status from your cell phone and get updates on all of the people you are following. If that is the case for you, go check it out. Maybe I'll become a regular twitterer when I get unlimited texting, and then I'll try to convince everyone I know to use it too.
